Vjetrenica (which means “wind cave” or “blowhole”) is the largest and most important cave in Bosnia and Herzegovina, and one of the most important caves in the Dinaric Alps mountain range, which is famous worldwide for its karstic and speleological riches. It is located in the Popovo field in Ravno, East Herzegovina in the Federation of Bosnia and Herzegovina.
Located in Popovo Polje in Ravno municipality, village Zavala with its old architecture and stone masonry, together with Vjetrenica cave, constitute the natural and architectural ensemble, which is in the process of being protected as National Monument of Bosnia and Herzegovina, and as such it is already placed on UNESCO Tentative List.
Vjetrenica cave is considered to have the richest cave fauna, with the highest rate of endemism. Vjetrenica cave also acquired fame throughout the world geological and biological scientific communities, as well as environmental communities around the country and the world for its imperiled and uncertain future, caused by unprofessional management lacking any expertise, and uncertain status at state and especially local level.
Despite all setbacks government of Bosnia and Herzegovina, although creepingly slowly, nominated Vjeternica to UNESCO Tentative List clearly expressing intention to protect the cave and its biodiversity and eventually inscribe it with UNESCO.
